Hi,
I have a Mikrotik (Hap Ac2) router which I got from my ISP. I then bought an additional HAP AC2 to extend my wifi range. I used a Lan cable to connect them.
If I want to connect I get (connected without internet).
I went to 198.168.88.1 to configure the router, however I have no Idea what I am doing.
Can anyone please assist to configure it with the correct settings.
Thanks in advance
Full configs of both devices
/export file=anynameyouwish ( minus router serial Number and any public WANIP information ).
If you can, please explain to me like I am a 5 year old 
I don’t have one of these to check the precise terminology used, but the essential idea is to apply the “AP bridge” QuickSet configuration on the second router. Clients that connect to it get bridged to the wired LAN and then can connect out through your ISP-provided hAP ac².
Assigning the same SSID (network name) and PSK (WiFi password) to the second ac² will make this more seamless. Clients will then automatically connect to whichever radio is stronger at that location.
/export file=anynameyouwish ( minus router serial number and any public WANIP information )
To export and paste your configuration (and I’m assuming you are using WebFig or Winbox), open a terminal window,
and type (without the quotes) “/export hide-sensitive file=any-filename-you-wish”. Then open the files section
and right click on the filename you created and select download in order to download the file to your computer.
It will be a text file with whatever name you saved to with an extension of .rsc. Open that file in your favorite
text editor and redact any sensitive information if desired / needed. Then in your message here, click the code
display icon in the toolbar above the text entry (the code display icon is the 7th one from the left and looks
like a square with a blob in the middle). Then paste the text from the file in between the two code words in brackets.
